At the moment it looks likely Expanding Horizons will, in the near future, move from a PW to a regular RP thread.

But what about all the RP threads?

What about all the character submissions?

I'm not exactly sure how the mechanics of that will work. For now I will say: if there's something in Expanding Horizons threads you'd need to continue the game, save that content now. I say that only because I can't predict exactly how such a transition will go, and it's better to be safe than sorry.
